    • 摘要: Cell cycle regulation plays a critical role in plant growth and development.In this study,the role of a tomato cell cycle gene SlCycB1 has been characterized.Expression analysis revealed that SlCycB1 was mostly expressed in stem,root,and leaves,with relative lower expression in flower and fruit.Tomato plants overexpressing SlCycB1 exhibited a reduction in cell number and increased cell size leading to the growth retardation.Furthermore,yeast two-hybrid analysis and bimolecular fluorescence complementation revealed that SlCycB1 interacted with histone H3.2,an essential component of the nucleosome.Histone H3.2 was transcriptionally up-regulated in the SlCycB1 overexpressing tomato lines.Furthermore,the overexpression of histone H3.2 in transgenic plants showed similar phenotypes to SlCycB1 overexpressing lines.Based on these findings,we concluded that SlCycB1 overexpression altered tomato architecture in association with histone H3.2.

    • 摘要: The BLU gene coding for zinc finger,MYND-type containing 10(ZMYND10)protein is mapped on chromosomal region 3p21.It is frequently lost in some kinds of cancers due to hypermethylation on its promoter region and identified as a tumour suppressor gene.The underlying mechanisms for BLU-mediated tumor suppression remain unclear.BLU has been reported to disturb cell cycle progression.The present study aims at examining whether ZMYND10 prevents progression of the cell cycle by targeting to repressive histone marks and downregulating the level of cyclins.Proteins structurally similar with ZMYND10 have been shown to recognize DNA sequence upstream of coding portion of the gene encoding cell cycle regulators.Enzymes,notably demethylases modifying the lysine residues are over-expressed line oncoproteins,and targeted in anti-cancer therapy.BLU was re-expressed in H1299 and HepG2 cells.The level of cyclin D1,cyclin B1 and trimethylate lysine 9 on histone 3(H3K9me3)and the binding of BLU with SIN3A(a component of the co-repressor)were detected.Cell cycle profile was measured.The evolutionary relationship between ZMYND10 and other ZMYND proteins was analysed by phylogenetic tree construction.We found that BLU expression induced G1 arrest in H1299 cells,and induced G1/G2 arrest in HepG2 cells.Cell cycle arrest was correlated with reduced activities and levels of cyclins;cyclin D1 was downregulated in H1299 cells;Both cyclin B1 and D1 were downregulated in HepG2 cells;and that BLU was associated with SIN3A.In both cell lines,the expression of H3K9me3 was induced.BLU was clustered with histone methyltransferase SMYD3 and SMYD1 on the same clade of the deduced phylogenetic tree.The results thus suggested that ZMYND10 encoded by BLU inhibited cyclins activity to prevent cell cycle progression through interaction with repressors and histone repressive marks to block the expression of genes coding for cyclins.

    • 摘要: Cell cycle regulation that plays a pivotal role during organism growth and development is primarily driven by cyclindependent kinases(CDKs)and Cyclins.Although CDK and Cyclin genes have been characterized in some animals,the studies of CDK and Cyclin families in molluscs,the ancient bilaterian groups with high morphological diversity,is still in its infancy.In this study,we identified and characterized 95 CDK genes and 114 Cyclin genes in seven representative species of molluscs,including Octopus bimaculoides,Pomacea canaliculata,Biomphalaria glabrata,Lottia gigantea,Mizuhopecten yessoensis,Crassostrea gigas and Aplysia californica.Genes in CDK and Cyclin families were grouped into eight and 15 subfamilies by phylogenetic analysis,respectively.It should be noted that duplication of CDK9 gene was detected in P.canaliculate,L.gigantea and M.yessoensis genomes,which has never been recorded in animals.It is speculated that duplication may be the main course of expansion of the CDK9 subfamily in the three molluscs,which also sheds new light on the function of CDK9.In addition,Cyclin B is the largest subfamily among the Cyclin family in the seven molluscs,with the average of three genes.Our findings are helpful in better understanding CDK and Cyclin function and evolution in molluscs.

    • 摘要: The mammalian protein kinase C-interacting cousin of thioredoxin(PICOT;also termed glutaredoxin 3)is a multi-domain monothiol glutaredoxin that is involved in a wide variety of signaling pathways and biological processes.PICOT is required for normal and transformed cell growth and is critical for embryonic development.Recent studies in T lymphocytes demonstrated that PICOT can translocate to the nucleus and interact with embryonic ectoderm development,a polycomb group protein and a core component of the polycomb repressive complex 2,which contributes to the maintenance of transcriptional repression and chromatin remodeling.Furthermore,PICOT was found to interact with chromatin-bound embryonic ectoderm development and alter the extent of histone 3 lysine 27 trimethylation at the promoter region of selected polycomb repressive complex 2 target genes.PICOT knockdown in Jurkat T cells led to increased histone 3 lysine 27 trimethylation at the promoter region of CCND2,a cell cycle-regulating gene which encodes the cyclin D2 protein.As a result,the expression levels of CCND2 mRNA and protein levels were reduced,concomitantly with inhibition of the cell growth rate.Analysis of multiple data sets from the Cancer Genome Atlas revealed that a high expression of PICOT correlated with a low expression of CCND2 in a large number of human cancers.In addition,this parameter correlated with poor patient survival,suggesting that the ratio between PICOT/CCND2 mRNA levels might serve as a predictor of patient survival in selected types of human cancer.

    • 摘要: BACKGROUND NIMA related kinase 2(NEK2) is closely related to mitosis, and it is currently considered to be over-expressed frequently in many poorly prognostic cancers.However, the effect of the up-regulated NEK2 on cellular signaling in tumors,such as gastric cancer(GC), is con-fusing.AIM To determine the role of the up-regulation of NEK2 in GC.METHODS To investigate the pathological significance of NEK2 in GC, the expression pattern of NEK2 in GC was investigated based on the 'Oncomain' database and compared between 30 pairs of cancer samples and adjacent tissues. The coexpression of NEK2 and ERK in GC was analyzed using The Cancer Genome Atlas(TCGA) database and confirmed in clinical samples by quantitative realtime PCR(qRT-PCR), and the survival curve was also plotted. Western blot or qRT-PCR was used to analyze the effect of NEK2 on the phosphorylation levels of ERK and c-JUN in two GC cell lines(BGC823 and SGC7901) with NEK2 overexpression, and the expression of the downstream effector cyclin D1.Furthermore, CCK8, EdU incorporation assay, and flow cytometry were used to detect the proliferative ability of BGC823 and SGC7901 cells with stably silenced ERK.RESULTS NEK2 was significantly up-regulated in human GC tissues. ERK was significantly associated with NEK2 expression in human clinical specimens, and combined overexpression of NEK2 and ERK potentially forecasted a poor prognosis andsurvival in GC patients. NEK2 knockdown in GC cells inhibited ERK and c-JUN phosphory-lation and reduced the transcription of cyclin D1. More interestingly,NEK2 can rescue the inhibition of cellular viability, proliferation, and cell cycle progression due to ERK knockdown.CONCLUSION Our results indicate that NEK2 plays a carcinogenic role in the malignant proliferation of GC cells via the ERK/MAPK signaling, which may be important for treatment and improving patient survival.

    • 摘要: BACKGROUND Esophageal cancer is one of the most common cancers around the world, and it has high incidence and mortality rates. The conventional therapy for esophageal cancer is radiotherapy, although its effect is highly limited by the resistance of esophageal cancer cells. Thus, strong radiosensitizers can be very crucial during radiotherapy against esophageal cancer. Brucea javanica oil emulsion (BJOE) is a widely used drug against various cancers, such as liver, colon, and ovarian cancer. However, its anti-cancer effect and mechanism and the use of BJOE as a radiosensitizer have not been explored in esophageal cancer. AIM To evaluate the anti-cancer effect and mechanism of BJOE and explore the potential use of BJOE as a radiosensitizer during radiotherapy. METHODS The inhibitory effect of BJOE and its enhancement function with radiation on cell viability were examined with the calculated half-maximal effective concentration and half-maximal lethal concentration. The influence of BJOE on cell migration and invasion were measured with EC109 and JAR cells by wound-healing and transwell assay. Clonogenesis and apoptotic rate, which was measured by Hoechst staining, were investigated to confirm its enhancement function with radiation. To investigate the molecular pathway underlying the effect of BJOE, the expressions of several apoptosis- and cycle-related proteins was detected by western blotting.cell lines more than normal cell lines, and it markedly reduced migration and invasion in esophageal cancer cells (EC109 and JAR). Moreover, it promoted cell apoptosis and enhanced the effect of radiotherapy against esophageal cancerous cells. In the viability test, the values of half-maximal effective concentration and half-maximal lethal concentration were reduced. Compared to the control, only around 1/5 colonies formed when using BJOE and radiation together in the clonogenic assay. The apoptotic rate in EC109 was obviously promoted when BJOE was added during radiotherapy. Our study suggests that the expression of the apoptosis-proteins Bax and p21 were increased, while the expression of Bcl-2 was stable. Further detection of downstream proteins revealed that the expression of cyclin D1 and cyclin-dependent kinase 4/6 were significantly decreased. CONCLUSION BJOE has a strong anti-cancer effect on esophageal cancer and can be used as a radiosensitizer to promote apoptosis in cancerous esophageal cells via the cyclin D1-cyclin-dependent kinase 4/6 axis.
